KIMM(Korea Institute of Machinery and Materials) and ROTEM have been leading development of the low to medium speed urban transit maglev for the past 20 years. The result of this long term national project is UTM-01 (Urban Transit Maglev -01) in 1998 and UTM-02 in 2006 and the 6.1 ㎞ long double track maglev commercialization project in Inchon international airport from 2006 to 2012. In this paper the status of the maglev development in Korea is reported.

This paper deals with the preliminary study on the HTSC levitation magnet for MAGLEV operating in persistent current mode (PCM). The high temperature superconducting (HTSC) levitation magnet consists of two single-pancake type coils wound with Bi-2223 wire and a persistent current switch (PCS). The levitation magnet was designed by using 3-D finite element analysis. The suspension system for high-speed electrodynamic suspension (EDS) maglev should operated in persistent current mode. It is important to develop a technology to minimize the joint resistance of splice between two HTSC wires. The PCS was observed with respect to various magnitude of charging current. Based on these results, the levitation system using HTSC wire will be further studied.
